According to Page Six, the punch was thrown after Bloom refused to shake Bieber’s hand. Bieber than allegedly then taunted Bloom about his ex-wife Miranda Kerr, remarking “She was good.”

In 2012, Bieber was seen cozying up to Bloom’s then wife backstage as the Victoria’s Secret Fashion Show. More recently, Orlando was spotted hanging out with Bieber’s on and off girlfriend, Selena Gomez.

That’s when Bloom allegedly took a swing at Bieber, which led the crowd to cheer.
